venting ?

I have a 3 1/2" vent and I would like to drain a 1 1/2" sink drain into it.
As long as the 1 1/2" is level how far away can it be from the 3 1/2" with
out it's own vent? I'm looking at about 3 1/2', is that to far? Should I
vent the sink also? Do I just runt the sink vent back into the 3 1/2" vent,
make it look like an "O"? Thanks for the help! dino
